IMPROVEMENT IN VAPOR-LAMPS.

Specification forming part of Letters Patent No. l 86,100, dated January 9, 1877 application filed August 3, 1876.

To all whom it may concern:

Be it known that I, JOSEPH BENSON, of South Boston, in the county of Suffolk, and State of Massachusetts, have invented Improvements in Vapor-Lamps, of which the following is a specilication:

This invention relates tO lamps for burning naphtha or other hydrocarbon oils, and the improvement consists in the combination of asbestus, mica, and cotton wicking within the wick-tube of the lamp.

ln the accompanying' plate Of drawings, Figure l is a central vertical section of my improved naphtha-lam p. Figs.2, 3, and 4, sections on lines :v w, yy, and z z, respectively.

In the drawings, A represents the lampbody, having handle'B,and naphtha-chamber C D, the wick-tube secured to a screw-cap, a, which screws into the screw-threaded opening bin the top ot' the lamp. The wick-tube D extends down into the naphtha-chamber O nearly to itsbottom. E,cotton wicking. This cotton wicking E enters the naphtha-chamber C, at the bottom Of the wick-tube, and extends up into the wick-tube for a portion of its length, where it meets with a filling of asbestus, F, which continues to the burner endfof the wick-tube, and within this filling there are a series of upright walls or partitions of mica, Gr, which are separated by the iilling, and end at the burning end Of the wick-tube. The cotton wick E draws the naphtha up the wick-tube, the mica partitions G conduct the heat to the naphtha, and the asbestus filling allows the vapor generated from the naphtha to escape to the burning end of the wicktube, tO be there burned, and by the combination of said three elements a most perfect combustion and illuminating llame are secured. H, the vent for safety and relief Of pressure of generated gases in the naphtha or chamber O.

This vent-tube is in the form Of a nipple, which is screwed into the upper portion of the lamp-body, and this nipple at its inner end for a portion Of its length is closely packed with wire gauze h, which allows the gases to pass out, but prevents the communication of llame tO the inside Of the lamp should the escaping gases, at the aperturel of the nipple, by any possibility ignite. o is the usual cap to wick-tube to prevent evaporation Of the naphtha when the lamp is not in use.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-

In a naphtha-lamp, the combination wick herein described, the same consisting of an asbestos filling, F. mica partitions G, and cotton wick E, applied within a wick-tube or casing, all substantially as described, for the purpose specified.
